FOREWORD
This document has been prepared by the Contract Laboratory Program (CLP) Sample Management
Office (SMO) specifically for the guidance and direction of program clients. The Sampler's Guide
to the CLP is designed to clarify sampling procedures necessary to submit samples for CLP
analysis. The Sampler's Guide to the CLP acts as a reference for the Regions and sampling
contractors to promote consistency in sampling procedures throughout the Regions and ensure the
proper adherence to CLP requirements. This document is intended to be used as a supplement to,
not a replacement for, existing Regional sampling instructions and should accompany the User's
Guide to the CLP to provide a thorough overview of the CLP.

SECTION I: THE CLP NETWORK
A. CLP Orientation
The CLP is a national program of commercial contractor laboratories for service to the ten
U.S. Environmental Protection Agency (EPA) Regions. The CLP supports EPA's
Superfund effort, a nationwide cleanup of designated hazardous waste sites. This effort
was originally established under the 1980 Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA) and presently exists under the 1986
Superfund Amendments and Reauthorization Act (SARA).
The CLP provides chemical analytical services using state-of-the-art technology for the
ten EPA Regions. The program is structured to ensure legally defensible analytical
results for use in supporting EPA enforcement actions or other user needs. To achieve
this goal, the CLP relies on its quality assurance procedures and detailed documentation.
The CLP's analytical programs are continually developed, managed and updated through
coordination by the National Program Office.
B . National Program Office
The CLP is directed by the National Program Office (NPO), in EPA Headquarter's
Analytical Operations Branch (AOB), Hazardous Site Evaluation Division (HSED), Office
of Solid Waste and Emergency Response (OSWER), located in Washington, D.C. The
NPO is comprised of the AOB Branch Chief, Regional Operations Section Chief and
personnel, and the Analytical Methods Implementation Section Chief and Administrative
Project Officers (APOs).
The NPO responsibilities include the following:
• developing and managing CLP objectives,
• generating, administrating and evaluating CLP analytical and support
services contracts,
• directing CLP quality assurance in coordination with overall OSWER
quality assurance activities, and
• policy and budget formation and implementation.
In coordinating Superfund sampling efforts, the NPO is supported by the Sample
Management Office (SMO), the Regional Technical Project Officers (TPOs), and the
Regional Sample Control Centers (RSCCs) (see Figure 1).
-------
Sample Management Office
The Sample Management Office (SMO) is contractor-operated and provides management,
operations, and administrative support to the CLP. SMO routinely receives Regional
analytical requests, coordinates and schedules sample analyses, tracks sample shipments
and analyses, receives and checks data for completeness and compliance, processes
laboratory invoices, and maintains a repository of sampling records and program data. In
addition, SMO supports procurement/IFB development, Statement of Work production,
and CLP meeting/conference coordination.
Regional Technical Project Officer
The Regional Technical Project Officer (TPO) monitors the technical performance of
contract laboratories located in his/her Region. The TPO works closely with the APOs in
responding to laboratory technical problems and leads laboratory on-site evaluations.
Regional Sample Control Center
The Regional Sample Control Center (RSCC) coordinates Regional sampling efforts and
serves as the central point of contact for sampling questions and problems. The RSCC
assists in coordinating the level of Regional sampling activities to correspond with the
monthly projected demand for analytical services.

SECTION II: ANALYTICAL SERVICES
The CLP provides a range of chemical analytical services to the user community through several
analytical programs. These programs include Routine Analytical Services (RAS), Special
Analytical Services (SAS), and RAS plus SAS requests.
A. Routine Analytical Services
Routine Analytical Services (RAS) are analytical services performed by laboratories who
have been awarded Government contracts under the CLP. These contractor laboratories
(CLP laboratories) operate under various analytical Statements of Work (SOWs) to
analyze specific environmental samples. RAS matrices include water and soil/sediments
only. Samplers may request an analytical fraction of each RAS program. For example,
RAS-VOAs may be ordered without RAS-semivolatiles or RAS-pesticides/aroclors.
However, RAS-pesticides may not be ordered without RAS-Aroclors as fractions may not
be split. The RAS programs are shown with their corresponding fractions and
concentrations in Figure 2.

B . Special Analytical Services
Special Analytical Services (SAS) are analytical services that allow greater flexibility
with parameters, matrices, methods, and data turnaround times than RAS. The EPA
Region defines its needs for the SAS through a SAS Client Request form and specifies
analytical methods and quality control requirements. SMO then arranges analytical
subcontracts with chosen laboratories to meet the requests of the Region.
The following are examples of SAS requests:
• Asbestos
• Radiochemistry
• Air analyses
• Oil and grease
• Geotechnical, e.g., grain size
C. RAS plus SAS
RAS plus SAS samples are analyzed for standard RAS parameters with additional SAS
requirements. The following circumstances exemplify RAS plus SAS:
• Analyzing for full organics with faster turnaround times than offered under
the full organics RAS program
• Analyzing for total metals, a RAS inorganic program, plus sulfate, which is
not available through RAS
• Analyzing for 2,3,7,8-PCDD and 2,3,7,8-PCDF In water samples
-------
SECTION III: SAMPLE COLLECTION
A. CLP Sample Definition
RAS Sample
A CLP RAS sample is defined as one matrix, either water or soil/sediment (never both).
The RAS sample is further defined as consisting of all the sample aliquots from one
station location, for each matrix and RAS analytical program. Therefore, one CLP
sample may consist of many bottles and vials.
For example, let's say you are sampling at Leroy's Pond. You are instructed to collect
one water sample and one soil/sediment sample each to be analyzed for full organics and
full inorganics. First, identify the fractions of the RAS analytical program. VOAs, SVs,
and pesticide/Aroclors all comprise the RAS full organics sample. Total metals and
cyanide fall under the RAS full inorganics program. So, you have two RAS analytical
programs, full organics and full inorganics.
Next, identify the sample matrix. Your instructions call for one water sample and one
soil/sediment sample for each RAS analytical program. Since you have identified two
RAS analytical programs, you must collect four separate samples: one water sample and
one soil/sediment sample to be analyzed for RAS organics and one water sample and one
soil/sediment sample to be analyzed for RAS inorganics (see Figure 3).
Since all of the filled containers for one matrix (water or soil/sediment) and one analytical
program (organic or inorganic) compose the sample, you will have more than one jar or
vial for each entire sample collection.

SAS Sample
CLP SAS samples may consist of unusual matrices such as oil, sludge, or dust depending
on the Region's specification. Requirements for SAS samples vary and are detailed in the
SAS subcontract. SAS samples must be indicated by a SAS number (see Section IV:
Sample Documentation). Consult your RSCC for details regarding the type of SAS
sample to collect.
RAS plus SAS Sample
RAS plus SAS samples are also determined by the Region. Follow RAS sample
collection procedures and fill out the SAS part of the analysis on the Traffic Report (TR)
(see Section IV: Sample Documentation). For example, a RAS plus SAS request may be
to analyze for total metals plus sulfate. In this case, follow the procedures for collecting
full inorganic samples and note that the sample is also to be analyzed for sulfate on the
inorganic TR.
-------
B . Sample Volume
The collection of proper sample volume is imperative to the success of sample analysis.
If you do not collect sufficient sample volume, the analysis of all required parameters and
complete quality control determinations may not be possible. Therefore, it is especially
important to note the volume requirements for each sample and to take care to collect the
amount specified.
The following tables show the requirements for sample volume collection and container
type for each RAS program and fraction. Container type codes are detailed in Section HI,
Part C, Sample Containers. Note: Collect water and soil samples for volatiles analysis
so that the containers are completely filled to the top with no air pockets.

D. Quality Control Samples
Quality control (QC) samples are used to estimate the precision and accuracy of analytical
results and to examine sources of error introduced by field and laboratory practices. The
amount and type of QC samples collected varies between Regions so always refer to
Regional guidance.
Assign each QC sample, except laboratory QC samples, a separate sample number and
transcribe it on the TR (see Section IV: Sample Documentation). The laboratory QC
sample is a special name for an existing sample required by the laboratory's contract; it is
not an additional sample. Assign laboratory QC samples the same number so that the
laboratory will not confuse them with the other samples for analysis. For the laboratory
QC sample, label the sample containers and all copies of the paperwork as "lab QC".
Figure 12 shows some of the types of QC samples that may be collected. Follow
volume requirements as specified in Part B.
E. Sample Preservation and Holding Times
Sample Preservation
Some samples must be preserved before shipment to the laboratory. In this case, preserve
samples immediately upon sample collection. Preservation techniques vary among the
Regions, so use the preservation information in Figure 13 as guidance for properly
preserving samples. Contact your RSCC for Region-specific instructions.
Holding Time
Samples should be analyzed as soon as possible after collection. Many samples are not
stable for lengthy periods following collection so daily shipment to laboratories is very
important. Holding time, listed in Figure 13, is the maximum amount of time that
samples may be held before analysis from time of collection and still be considered valid.
Samples exceeding these holding times are not valid and must be retaken. Please note
that the following are technical holding times and are not contractually determined.

zMaximum holding time is 24 hours when sulfide is present. Optionally all samples may be tested
with lead acetate paper before the pH adjustment in order to determine if sulfide is present. If sulfide
is present it can be removed by the addition of cadmium nitrate powder until a negative spot test is
obtained. The sample is filtered and then NaOH is added to pH 12.
3 Should only be used in the presence of residual chloride.
^For samples from non-chlorinated drinking water supplies concentrated H2SO4 should be added to
lower sample pH to less than 2. The sample should be analyzed within 14 days after sampling.

SECTION IV: SAMPLE DOCUMENTATION
Each sample processed by the CLP must be properly documented to ensure timely analysis of all
parameters requested and to support the use of the sample data in potential enforcement actions. It
is your responsibility to fill out all appropriate paperwork completely and correctly. This section
provides instructions for completing all CLP forms and other sample documentation. Your
Region may require additional documentation, if so, contact your RSCC for Region-specific
instructions and guidance prior to the sampling activity.
A. Sample Number (RAS Programs)
The CLP sample number is a unique number that identifies each sample under a RAS
analytical program. The sample number is preprinted on adhesive labels (Figures 14 and
15) and provided to you from the RSCC which routinely orders them from SMO. It is
your responsibility to assign this critical sample number correctly and to transcribe it
accurately on the appropriate documentation. Place the label on the appropriate sample
container and transcribe the sample number onto the sample tag.
Organic and VOA-only Sample Numbers
Organic and VOA-only sample numbers are five digits in length and have the format
XX123. Larger volume Regions may have six digit organic sample numbers in the
format XXX123. Organic and VOA-only sample numbers are preprinted on 10 labels per
strip: four for extractables, two for VOAs, and
four blank (extra). DESTROY ALL UNUSED

LABELS to prevent duplication of sample
numbers.
Inorganic Sample Numbers
Inorganic sample numbers are six digits in
length and have the format MXX123. Larger
volume Regions may have seven digit
inorganic sample numbers in the format
MXXX123. Inorganic sample numbers are
preprinted on seven labels per strip: two for
total metals, two for cyanide and three extra.
Remember that the unique sample number
must only be used for one sample. DESTROY

-------
B. Case Number
A Case number is assigned by SMO to RAS and RAS plus SAS samples and is five
digits in length. Each sampling event receives a distinct Case number which helps
maintain site confidentiality. The Case number also enables SMO and the Region to
easily track RAS and RAS plus SAS samples.
Example: Case No. 10414
C. SAS Number
SAS samples are designated by a SAS number assigned by SMO. The SAS number is
four numerical digits in length plus a letter suffix which indicates the Region. Like RAS
Case numbers, the SAS number assists in tracking samples and maintains site
confidentiality. Contact your RSCC for SAS sample labels.
Example: SAS No. 4100-E
The "E" suffix indicates that the sample has come from Region V.
Individual SAS samples are numbered using the SAS number followed by a two digit
number beginning with "01".
Example: SAS No. 4100-E-01
D. RAS plus SAS Numbers
RAS Plus SAS samples receive both a Case number and a SAS number.
Example: Case No. 10458. SAS No. 4100-E
17
-------
E. Traffic Report
The Traffic Report (TR) enables SMO and the Region to track samples and ensure that the
samples are shipped to the appropriate contract laboratory. The TR includes a chain-of-
custody record which is located at the bottom of the form. The form is used as physical
evidence of sample custody. According to EPA enforcement requirements, official custody
of samples must be maintained and documented from the time of collection until the time
the samples are introduced as evidence in the event of litigation. You are responsible for
the care and custody of the sample until sample shipment.
A sample is considered to be in your custody if any of the following criteria are met:
1. The sample is in your possession or is in your view after being in your
possession,
2. The sample was in your possession and then locked up or sealed to prevent
tampering, or
3. The sample is in a secured area.
Document RAS organic and inorganic samples on separate CLP sample TR forms. TR
forms must be completed for every shipment of RAS samples to a contract laboratory.
Use ink only, no pencil! Each TR documents up to 20 samples per Case number
and sample shipment. A separate TR must accompany each daily shipment. Make
corrections by drawing a line through and initializing the error, then enter the correct
information. Erasures are not allowed!
When an individual sample is to be analyzed for RAS plus SAS, use the appropriate TR,
organic or inorganic. Instructions summarizing CLP sample volumes, packaging and
reporting requirements are printed on the back of the TRs. Check with your RSCC for
RAS plus SAS required volumes.
The following is a list of step-by-step instructions for properly completing the organic
and inorganic Traffic Reports. The numbers refer to specific boxes on the TR form
example (Figures 17 and 18). Please follow along with the completed TR form example.

SECTION V: SAMPLE PACKAGING AND SHIPPING
A. Sample Packaging
Follow all state and federal regulations governing hazardous environmental
sample packaging and shipment.
Use waterproof metal or hard plastic ice chests or coolers for shipping
samples. Line the cooler with plastic before inserting samples.
Enclose sample containers in clear plastic bags inside the cooler. Make sure
that sample tags and labels are visible.
Inorganic samples and VGA water samples may require chemical
preservation. Refer to Section ffl: Sample Preservation for these techniques
before packaging.
Any samples suspected to be of medium/high concentration or containing
dioxin must be enclosed in a metal can with a clipped or scalable lid (e.g.,
paint cans). Label the outer metal container with the sample number of the
sample inside.
"Double bag" sample containers which do not fit into paint cans before
placing them in the cooler.
Figure 22. Sample Packaging
Clear plastic
bag
Sample
Container
Metal Paint Can
Pack shipping containers with noncombustible, absorbent packing material
such as vermiculite. Place this packing material around the sample bottles
or metal cans to avoid breakage during shipment. Never use earth or ice to
pack samples as earth is a contaminant and ice melts which may cause
complications.
Cool water samples for low/medium organic analysis and low/medium level
metals and cyanide analysis to 4° C with ice or "blue ice" when shipping.
Seal the ice in plastic bags to prevent melting ice from soaking the packing
material.
27
-------
Write a return name and address for the sample cooler on the inside of the lid
in permanent ink to ensure the return of the cooler.
Enclose all sample documentation (i.e., TRs, SAS PLs, Chain-of-Custody
Records) in a waterproof plastic bag and tape the bag to the underside of the
cooler lid. If more than one cooler is being used, place all documentation in
one cooler.
Figure 23. Sample Cooler
SAMPLE DOCUMENTATION
Seal coolers with custody seals so that if the cooler was opened, the custody
seal would be broken. Place clear tape over the custody seal to prevent
damage to the seal. Also, tape the cooler shut with packing tape over the
hinges and place tape over the cooler drain.
CUSTODY SEALS
28
-------
B . Sample Shipping
• Place return address labels clearly on the outside of the cooler.
• Ship samples through a commercial carrier, such as Federal Express, Emery,
Purolator or equivalent.
• Fill out all required Government and commercial carrier shipping papers
according to U.S. Department of Transportation and commercial carrier
regulations.
• Ship all samples by overnight delivery.

Potential Sampling Problems
Sometimes problems may arise during sampling from improper sampling practices or
other reasons. Some of these problems are shown in the following list.
• Filling out paperwork incorrectly or incompletely
• Collecting less than the required sample volume
• Shipping samples to the wrong laboratory
• Collecting matrices other than water or soil/sediment (i.e., rocks, leaves,
sticks, etc.)
• Using incorrect sample containers
• Leaking sample containers
• Equipment malfunctions
Severe weather conditions
These problems may delay sample analysis. If any of these problems occur, contact your
RSCC or SMO immediately for instructions on how to deal with the problem.
29
-------
D. Reporting Sample Shipment
Notify your RSCC or SMO, as directed, of all sample shipments on the day of shipment.
This notification enables SMO to track the shipment of samples from the field to the
laboratory and ensure timely laboratory receipt of samples. Contact SMO (703/557-2490)
with the following information:
• Your name, phone number and Region.
• Case number and/or SAS number of the project.
• Batch numbers (dioxin only).
• Exact number(s), matrix(ces) and concentration(s) of samples shipped.
• Laboratory(ies) to which samples were shipped.
• Carrier name and airbill number(s) for the shipment.
• Method of shipment (e.g., overnight).
• Date of shipment.
• Suspected contaminants associated with the samples or site.
• Information on completions, changes, delays, continuations, etc., pertinent to
the Case and sampling project.
Sample shipments made after 5:00 p.m. EST should be called in to SMO at the start of
business the next day (8:00 a.m. EST). You must notify SMO by 3:00 p.m. EST Friday
for sample shipments that will be delivered on Saturday.

SECTION VI: COMMUNICATION NETWORK
You have two primary contacts for information or aid regarding sampling. The first contact is the
Region's Primary Regional Sample Control Center (RSCC) and the second contact is the SMO
Regional Coordinator. These two individuals will answer any questions and advise you as to the
best way to resolve problems in the field.
Figures 24 and 25 give names, addresses, and telephone numbers of Regional Primary RSCCs and
SMO Regional Coordinators. Contact only the Region to which you have been assigned. Note
that these individuals are subject to change.
